Okay just thought I would make this thread to sum up how I got my stuff working and what I learned so fare.

What platforms does it run on:Windows Only
There is no linux binaries.Source

Does sourcemod/metamod work:No cause it seems like it is a new engine branch, a mix betwen L4D2 & Portal 2Source

Steam Library Errors

Code:

Unable to load Steam support library.
This server will operate in LAN mode only.

There are 2 ways you are suppose to be able to fix this.
One Run Steam on the server (Yah the client)
Two try this (Not confirmed?)

Update: Should be working now, and it is, but if you do not run the steam client the steam group will not work!

Branding a Server
Well so fare it seems like you should be able to set some sort of banner, but I can't find any where it is displayed (Look in the host.txt file)
So atm it looks like a shit deal to host.

Community Servers / Steam Group Servers
It got the 2 same cvars as Left 4 Dead 1/2

Code:

// The ID of the steam group that this server belongs to. You can find your group's id under your group mangement
sv_steamgroup <id>

// If set, only members of Steam group will be able to join the server when it's empty
sv_steamgroup_exclusive 0

Command line for running the game

Code:

-game swarm -console +ip <ip> -port <port> +maxplayers 4 +map lobby

Also it seems like you need to start in the Lobby no matter what, also 4 players seems to be max.

Swarm.exe
No idea what this is for, it is in the root but yah.....
